WASHING-MACHINE.

SPECIFICATION forming part of Letters Patent NO. 496,936, dated May 9,1893- Application filed May 25, 1892. Serial 110.434 .301. (No model.)

by springs and composed of rollers and ribbed feed boards. This class ofwashing machines is illustrated by the patents of Abraham I-Iuffer, No.17,377, dated May 26, 1857, No. 18,642, dated November 17, 1857, and No.246,777, dated September 6, 1881.

The present improvements are illustrated in the accompanying drawings,wherein Figure 1, is a central vertical longitudinal section of themachine. Fig. 2, is a crosssection thereof in a plane indicated by theline 22 in Fig. 1. Fig. 3, is a perspective of the roller bed. Fig. 4,is a perspective View of the bracket. Fig. 5, is aview of a portion ofone side of the machine. Fig. 6, is a horizontal section thereof. Fig.7, is a View of a portion of the other side of the machine. Fig. 8, is ahorizontal section thereof. Figs. 9, and 10, are perspective views ofthe bearings.

The washing machine comprises a water box A, supported on suitable legs,and having sides a a and bottom I). Secured to the sides of the box,just above the bottom, are four metallic brackets B, one at each corner.Each of the brackets has a vertical stem 0, along the side of the box,which constitutes a guide (as will hereinafter appear), and avertically-extending stud d on a horizontal stem 6 extending inwardlyjust above the bottom 12 of the box.

The concave roller bed 0, is composed of a frame having end rails ff,and two downwardly arched metallic side rails g g, which are providedwith apertures constituting bearings for the bosses h h of the rollers it' which extend between the rails or g. Each side rail g is at each endprovided with a vertical recess Z which cooperates with one of the fixedguides c. When placed in the water box, the

roller bed is elastically supported on the bottom thereof by coiledsprings D, one at each proper position and prevent it being moved 6olongitudinally within the water box when the washing machine isin use.At the same time the guides 0 do not interfere with the removal andinsertion of the roller bed in the water box.

At each end of the water box is an inclined ribbed feed and scrub boardE. Each board E is composed preferably of galvanized sheet iron. Eachboard has upwardly projecting ears m m, by means of which it is pivotedto the sides a of the water box near one end. The upper end of the feedboardis below the upper edge of the water box, so that the water willnot run up the feed board and splash over the end of the box; and thelowerend of the feed board rests upon one end rail f of the roller bed.The feed boards are independent of the roller bed, and can be turned upout of the Way (as shown in dotted lines in Fig. 1), when it is desiredto remove the roller bed from the box. Since the feed boards are thusentirely distinctand separate from the roller bed, the handling of thelatter is greatly facilitated.

Each feed board is preferably hollow,with perforations or apertures n inthe bottom plate. Vapor and steam from the hot water enter the interiorof the feed board through these apertures, and thereby maintain the feedboard hot, thus aiding the washing.

The rotary ribbed roller F, is carried by an axle 0, having an operatingcrank 19, exterior to the water box, and journaled in bearings G, H, atthe sides of the box. To enable, the roller bed to be removed, theroller F, must also be removable, and to enable this to be done thebearings G, H, are made removable.

The present invention, as regards the refit in grooves t, in the sidesof the bearing G.

. The inner flangettconstitutingthe inner side walls of the grooves 15,closes the slot 9 on the inside and prevents the escape of water. Thebearing G, is maintained firmly in place in the slot by a provisionconsisting of a link I, pivoted at one end to the exterior of side walla and carrying a screw Stud 12 at its outer end which enters an apertureto in the bearing G and seats against the bearing. By screwing this studup tight, the outer flange 0c (constituting the outer side walls of thegrooves t) is forced tightly against the outer face of side wall a, ofthe box, thus renderingthe same water tight. This bearing G, is the onethrough which the end of shaft 0, extends to which the crank handlep isattached. The link I, it will be noted,does not interfere with the crankhandle. An outwardly-projecting ear g on the bearing G, affords a handlefor lifting the bearing G, out of the slot q. The bearing G, extendsclear to the bottom of the slot q, so that the flange 0c preventsleakage at the bottom of the slot as well as at its sides. The slot qfor the other bearing H, is rendered water tight by means of a provisionconsisting of a plate J, secured to the outer face of the side wall a,covering the lower part of the slot. The bearing II, is

similar in its construction to bearing G, except that the lower part ofouter flange 00 is cut away, and the bearing H, need not extend to thebottom of the slot q. The screw stud a (corresponding to the screw stud'v of bearing G) extends through the plateJ and seats into a hole to inbearing H. The bearing is thus held tightly in place and prevented frombeing accidentally lifted.

To remove the roller F, with its bearings G, H, it is only necessary tounscrew the screw studs 1) 2 far enough to clear the apertures w in thebearings.

I claim as my invention 1. In a Water box, the roller bed removablymounted therein,and the removable roller,in combination with the feedboards located wholly within the water box independent of the roller bedand each pivotally connected with the box at one end thereof and extending therefrom when in operative position to the roller bed,substantially as set forth.

2. The fixed brackets within the water box, having guides c for theroller bed, and holding studs 01 for the springs of the roller bed, incombination with the roller bed having grooves or recesses Z fittingsaid guides c, and having springs D, at each corner which fit over saidstuds d, substantially as set forth.

3. The slotted side wall, and the bearing G, entering the slot in saidside wall, and having outer flange m, in combination with the pivotedlink I, and the screw-stud extending through said link and seatingagainst said bearing G, substantially as set forth.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
